One or more devices of a self-organizing network (SON), comprising: one or more processors; and memory communicatively coupled to the one or more processors, the memory configured to store one or more SON tools and a visualization tool, wherein the one or more SON tools, when operated by the one or more processors, perform operations comprising: receiving one or more performance indicators indicative of network usage in a first portion of a frequency spectrum in which the SON is operating, the first portion of the frequency spectrum being designated for use by a public service user while allowing use by one or more non-public service users; and determining, based on the one or more performance indicators, that network usage in the first portion of the frequency spectrum satisfies a first usage threshold of the first portion of the frequency spectrum; wherein the visualization tool, when operated by the one or more processors in response to the one or more SON tools determining that the network usage satisfies the first usage threshold, perform operations comprising: invoking the one or more SON tools to: transition the one or more non-public service users from the first portion of the frequency spectrum to a second portion of the frequency spectrum different from the first portion by generating an updated network configuration based at least in part on the one or more performance indicators and providing the updated network configuration to a base station of the SON, wherein a call session of the transitioned one or more non-public service users is maintained within the frequency spectrum during the transitioning, and hinder the one or more non-public service users from returning to the first portion from the second portion; and causing devices associated with the one or more non-public service users to display a notification that the one or more non-public service users have been transitioned from the first portion of the frequency spectrum to the second portion of the frequency spectrum based on the updated network configuration.
2. The one or more devices of the SON of claim 1 , wherein the SON tools are further configured to receive registration of the public service user in the first portion of the spectrum, wherein receiving registration of the public service user results in network usage within the first portion satisfying the first usage threshold.
Self-Organizing Network (SON) systems manage wireless network resources to optimize performance. A challenge in such systems is efficiently allocating spectrum, particularly for public safety users who require guaranteed access during emergencies. Existing solutions may not dynamically adjust spectrum allocation based on real-time usage patterns, leading to inefficiencies or service disruptions. This invention enhances SON systems by enabling dynamic spectrum management for public service users. The system includes SON tools that monitor spectrum usage in a first portion of the spectrum designated for public safety. When a public service user registers for access, the system evaluates whether network usage in that portion meets a predefined threshold. If the threshold is satisfied, the SON tools can trigger actions such as reallocating spectrum, adjusting power levels, or prioritizing traffic to ensure reliable service. The system ensures that public safety users gain access without disrupting existing network operations, improving reliability during critical situations. The solution integrates with existing SON frameworks, providing a scalable approach to spectrum management.
3. The one or more devices of the SON of claim 1 , wherein the SON tools are further configured to associate a weight with the one or more non-public service users, wherein hindering the one or more non-public service users from returning to the first portion of the spectrum is based at least in part on the weight.
Self-Organizing Network (SON) systems manage wireless spectrum allocation to optimize network performance. A challenge in these systems is efficiently handling non-public service users (e.g., private networks or specialized devices) that may disrupt spectrum usage for public services. Existing SON tools may lack mechanisms to prioritize or penalize non-public users based on their impact on spectrum efficiency. The invention improves SON systems by introducing a weighting mechanism for non-public service users. The SON tools assign a weight to each non-public user, which influences whether they are restricted from accessing a portion of the spectrum. The weight may reflect factors like usage patterns, interference potential, or service priority. When determining whether to hinder a non-public user from returning to a previously allocated spectrum portion, the SON tools consider this weight. For example, a higher weight may indicate lower priority, leading to restrictions, while a lower weight may allow continued access. This approach dynamically balances spectrum allocation between public and non-public services, improving overall network efficiency and fairness. The system may also include SON tools that monitor spectrum usage, detect conflicts, and adjust allocations accordingly.
4. The one or more devices of the SON of claim 1 , wherein hindering the one or more non-public service users from returning to the first portion of the spectrum includes determining an access class of the one or more non-public service users, and blocking the one or more non-public service users from returning to the first portion based at least in part on the access class.
This invention relates to self-organizing network (SON) systems for managing spectrum allocation in wireless communication networks, particularly in scenarios where spectrum sharing between public and non-public services is required. The problem addressed is ensuring that non-public service users do not re-enter a portion of the spectrum that has been temporarily allocated to public services, which could disrupt ongoing communications. The system includes one or more devices that monitor spectrum usage and dynamically allocate portions of the spectrum between public and non-public services. When a portion of the spectrum is allocated to public services, the system prevents non-public service users from returning to that portion. This is achieved by determining the access class of the non-public service users and blocking their access based on their class. The access class may indicate priority levels or service types, allowing the system to enforce restrictions selectively. By dynamically adjusting access based on access class, the system ensures efficient spectrum utilization while maintaining service quality for both public and non-public users. The invention improves spectrum sharing by preventing unauthorized re-entry, reducing interference, and optimizing resource allocation.
5. The one or more devices of the SON of claim 1 , wherein the first usage threshold comprises a dynamic threshold, and wherein the one or more SON tools are configured to modify the dynamic threshold based on the one or more performance indicators.
Self-optimizing networks (SON) are used in wireless communication systems to automatically optimize network performance by adjusting parameters such as cell coverage, capacity, and interference. A challenge in SON systems is determining appropriate thresholds for triggering optimization actions, as static thresholds may not adapt to changing network conditions or performance demands. This invention addresses this issue by introducing a dynamic threshold for network usage, which is adjusted based on real-time performance indicators. The SON system includes tools that monitor key performance metrics, such as signal strength, data throughput, or user load, and dynamically modify the usage threshold in response to these indicators. For example, if performance degrades due to increased traffic, the threshold may be lowered to trigger earlier optimization actions, such as load balancing or cell reselection. Conversely, if performance improves, the threshold may be raised to reduce unnecessary adjustments. This adaptive approach ensures that the SON system responds more effectively to varying network conditions, improving efficiency and user experience. The dynamic threshold is continuously updated to reflect current network state, enabling proactive optimization rather than relying on fixed, preconfigured values.
6. The one or more devices of the SON of claim 1 , wherein hindering the one or more non-public service users from returning to the first portion of the frequency spectrum comprises assigning a weight to the first portion of the frequency spectrum.
This invention relates to self-organizing networks (SON) in wireless communication systems, specifically addressing the challenge of managing frequency spectrum usage to optimize network performance. The technology focuses on preventing non-public service users from re-entering a designated portion of the frequency spectrum after they have been excluded. To achieve this, the system assigns a weight to the first portion of the frequency spectrum, which influences scheduling decisions to prioritize or deprioritize access to that portion. The weight assignment can be dynamically adjusted based on network conditions, user demand, or service requirements. This mechanism ensures that critical or high-priority services maintain uninterrupted access to the spectrum while limiting interference from non-public users. The solution enhances spectrum efficiency and reliability, particularly in environments where multiple users compete for limited resources. The invention is part of a broader SON framework that automates network configuration and optimization, reducing manual intervention and improving overall system performance.
7. The one or more devices of the SON of claim 1 , wherein the SON tools are further configured to automatically reconfigure the base station, based on the updated network configuration, to affect transfer of the one or more non-public service users to the second portion of the frequency spectrum.
This invention relates to self-organizing network (SON) tools for managing wireless communication networks, specifically addressing the challenge of dynamically reconfiguring network resources to optimize service for non-public network (NPN) users. The system includes one or more devices implementing SON tools that monitor network conditions and user traffic patterns. When a network configuration update is detected, the SON tools automatically adjust the configuration of a base station to facilitate the transfer of non-public service users to a designated portion of the frequency spectrum. This ensures efficient use of spectrum resources while maintaining service quality for specialized users. The base station reconfiguration may involve adjusting transmission parameters, allocating specific frequency bands, or modifying scheduling algorithms to prioritize non-public network traffic. The system dynamically adapts to changing network demands, improving spectrum utilization and reducing interference for non-public services. The invention is particularly useful in scenarios where non-public networks coexist with public networks, requiring flexible and automated spectrum management to meet regulatory and operational requirements.
8. A computer-implemented method, comprising: receiving, by one or more self-organizing network (SON) tools, one or more performance indicators indicative of network usage in a first portion of a frequency spectrum in which a SON is operating, the first portion of the frequency spectrum designated for use by a public service user while allowing use by one or more non-public service users; determining, by the one or more SON tools based on the one or more performance indicators, that network usage in the first portion of the frequency spectrum satisfies a first usage threshold of the first portion; and in response to determining, by the one or more SON tools, that the network usage satisfies the first usage threshold: invoking, by a visualization tool, the one or more SON tools to: generate an updated network configuration based at least in part on the one or more performance indicators and providing the updated network configuration to a base station of the SON, transition the one or more non-public service users from the first portion to a second portion of the frequency spectrum different from the first portion, wherein a call session of the transitioned one or more non-public service users is maintained within the frequency spectrum during the transitioning, and hinder the one or more non-public service users from returning to the first portion from the second portion; and displaying, by the visualization tool, on devices associated with the one or more non-public service users that the one or more non-public service users have been transitioned from the first portion of the frequency spectrum to the second portion of the frequency spectrum based on the updated network configuration.
This invention relates to self-organizing network (SON) tools for managing frequency spectrum usage in wireless networks, particularly in scenarios where a shared spectrum is designated for both public service users (e.g., emergency services) and non-public service users (e.g., commercial users). The problem addressed is ensuring reliable access for public service users while dynamically managing non-public service users to avoid interference. The method involves receiving performance indicators from SON tools, which monitor network usage in a shared frequency spectrum portion designated for public service users but also accessible to non-public users. If network usage exceeds a predefined threshold, the SON tools trigger an automated response. A visualization tool then invokes the SON tools to generate an updated network configuration, which is sent to a base station. This configuration transitions non-public users from the congested portion to a different part of the spectrum while maintaining their active call sessions. The system also prevents these users from returning to the original portion to ensure public service priority. Finally, the visualization tool notifies the affected users of the transition via their devices. This approach optimizes spectrum allocation dynamically, ensuring public service reliability while minimizing disruption to non-public users.
9. The method of claim 8 , wherein the SON comprises a telecommunication network, and the first portion of the frequency spectrum comprises a first frequency band.
A method for managing frequency spectrum allocation in a self-organizing network (SON) within a telecommunication network. The SON dynamically allocates frequency bands to optimize network performance. The method involves dividing the available frequency spectrum into at least two portions, where the first portion is a specific frequency band. The SON monitors network conditions, such as interference levels, traffic load, and signal quality, to determine the optimal allocation of the first frequency band. Based on this analysis, the SON adjusts the allocation of the first frequency band to different network elements, such as base stations or user devices, to improve overall network efficiency. The method may also involve coordinating with other network elements to ensure that the allocation changes do not disrupt ongoing communications. The goal is to dynamically adapt the frequency band usage to changing network conditions, reducing interference and improving data throughput. The SON may use machine learning or predictive algorithms to anticipate future network demands and preemptively adjust the frequency band allocation. This approach enhances spectral efficiency and ensures better resource utilization in the telecommunication network.
10. The method of claim 8 , further comprising modifying the threshold based at least in part on network usage within the first portion of the frequency spectrum.
This method also adjusts the point at which it switches to a different frequency band based on how busy the current frequency band is.
11. The method of claim 8 , wherein the one or more performance indicators comprise one of a power utilization, resource level, or interference level.
A system and method for monitoring and optimizing network performance in wireless communication networks. The technology addresses the challenge of efficiently managing network resources to ensure optimal performance, reduce power consumption, and minimize interference. The method involves collecting and analyzing performance indicators from network devices to assess their operational status. These indicators include power utilization, resource levels, and interference levels. By monitoring these metrics, the system can identify inefficiencies, such as excessive power consumption or high interference, and take corrective actions to improve network performance. The method may involve adjusting transmission parameters, reallocating resources, or implementing power-saving measures based on the analyzed data. This approach ensures that network devices operate efficiently while maintaining high performance and reliability. The system is particularly useful in environments where energy efficiency and interference management are critical, such as in dense urban areas or large-scale wireless networks. The method provides a dynamic and adaptive solution to optimize network operations in real-time, enhancing overall system efficiency and user experience.
12. The method of claim 8 , wherein the one or more non-public service users are characterized by a first QOS class and the public safety user is characterized by a second QOS class different from the first class, wherein the transitioning is based at least in part on the first class.
This invention relates to wireless communication systems, specifically managing quality of service (QoS) for different user types during network congestion. The problem addressed is ensuring reliable communication for public safety users while balancing service for non-public users in shared network environments. The method involves prioritizing network resources based on QoS class distinctions. Non-public service users are assigned a first QoS class, while public safety users are assigned a distinct second QoS class. When network congestion occurs, the system transitions service allocation by prioritizing public safety users over non-public users. The transition is determined at least partially by the first QoS class of non-public users, allowing dynamic adjustment of resource allocation to maintain critical communications for emergency services. The method may include monitoring network conditions, identifying congestion, and dynamically reallocating bandwidth or other resources. It may also involve preempting non-public user sessions or reducing their QoS to free up capacity for public safety communications. The system ensures that public safety users receive uninterrupted, high-priority service even under heavy network load, while non-public users experience controlled degradation or temporary service interruptions. This approach enhances reliability for emergency communications while optimizing overall network efficiency.
13. The method of claim 8 , further comprising receiving registration of the public service user in the first portion of the frequency spectrum, wherein receiving registration of the public service user results in network usage within the first portion satisfying the first usage threshold.
This invention relates to wireless communication systems, specifically managing spectrum usage between public safety and commercial services. The problem addressed is ensuring reliable access to spectrum for public safety users while optimizing commercial network efficiency. The system dynamically allocates spectrum between a first portion for public safety and a second portion for commercial use, adjusting based on usage thresholds. When public safety usage in the first portion exceeds a predefined threshold, the system automatically reallocates additional spectrum from the commercial portion to maintain public safety operations. Conversely, when commercial usage in the second portion exceeds its threshold, the system reallocates spectrum from the public safety portion to support commercial demand. The method includes monitoring usage in both portions, comparing it to the thresholds, and dynamically reallocating spectrum as needed. Additionally, the system registers public safety users in the first portion, and this registration triggers spectrum reallocation if it causes the first portion's usage to meet or exceed the threshold. The invention ensures prioritized access for public safety while maximizing commercial network efficiency through adaptive spectrum management.
14. The method of claim 8 , further comprising associating a weight with the one or more non-public service users, wherein hindering the one or more non-public service users from returning to the first portion of the frequency spectrum is based at least in part on the weight.
This invention relates to wireless communication systems, specifically methods for managing spectrum usage to mitigate interference from non-public service users. The problem addressed is the disruption caused by unauthorized or non-public users operating within a frequency spectrum designated for public safety or critical services, which can degrade performance and reliability. The method involves detecting the presence of one or more non-public service users in a first portion of the frequency spectrum reserved for public safety or other priority services. Upon detection, the system hinders these users from continuing to operate in that portion of the spectrum. The hindering action may include transmitting interference signals, adjusting power levels, or reallocating resources to force the non-public users to vacate the spectrum. A key aspect of the invention is the assignment of a weight to each non-public service user, which influences the severity or method of hindering their operation. The weight may be based on factors such as the user's interference level, persistence, or priority status. For example, a higher weight could trigger more aggressive interference mitigation, while a lower weight might result in a gentler approach. The system dynamically adjusts its response based on these weights to balance spectrum protection with fairness and efficiency. This approach ensures that critical services maintain reliable access to their designated spectrum while minimizing unnecessary disruption to non-public users. The method is particularly useful in shared or contested spectrum environments where multiple users compete for limited resources.
15. The method of claim 8 , wherein hindering the one or more non-public service users from returning to the first portion of the frequency spectrum includes determining an access class of the one or more non-public service users, and blocking the one or more non-public service users from returning to the first portion based at least in part on the access class.
This invention relates to wireless communication systems, specifically methods for managing access to frequency spectrum portions used by public safety and other critical services. The problem addressed is ensuring that non-public service users (e.g., commercial or general users) do not disrupt or interfere with critical communications by re-entering a frequency spectrum portion previously allocated to public safety services. The method involves dynamically controlling access to a first portion of the frequency spectrum, which is initially reserved for public safety or other priority services. When this portion is temporarily unused, non-public service users may be allowed to access it. However, to prevent interference when the priority service resumes, the method includes mechanisms to hinder these users from returning to the first portion. This is achieved by determining the access class of the non-public service users and blocking their return based on this classification. Access classes may categorize users by priority, service type, or other criteria, allowing selective restriction. The blocking may involve signaling, authentication checks, or other technical means to enforce the restriction. This ensures that only authorized or lower-priority users are temporarily granted access, while critical services maintain uninterrupted operation. The approach improves spectrum efficiency while protecting priority communications.
16. A method associated with a self-organizing network (SON), the method comprising: receiving, with one or more SON tools, one or more performance indicators indicative of network usage in a first portion of a frequency spectrum in which the SON is operating, the first portion of the frequency spectrum being designated for use by a public service user while allowing use by one or more other users; determining, with one or more engineering tools of the one or more SON tools and based on the one or more performance indicators, that network usage in the first portion of the frequency spectrum satisfies a first usage threshold of the first portion; and in response to determining, by the one or more SON tools, that the network usage satisfies the first usage threshold: generating, with the one or more engineering tools, an updated network configuration, invoking the one or more SON tools, by a visualization tool, to: transition one or more non-public service users from the first portion of the frequency spectrum to a second portion of the frequency spectrum different from the first portion, wherein a call session of the transitioned one or more non-public service users is maintained within the frequency spectrum during the transitioning, and hinder the one or more non-public service users from returning to the first portion from the second portion; and displaying, by the visualization tool, a notification on devices associated with the one or more non-public service users that the one or more non-public service users have been transitioned from the first portion of the frequency spectrum to the second portion of the frequency spectrum based on the updated network configuration.
In wireless communication networks, spectrum sharing between public service users (e.g., emergency services) and other users can lead to congestion, particularly when public service users require priority access. This invention addresses the challenge of dynamically managing spectrum usage to ensure public service users have uninterrupted access while minimizing disruption to other users. The method involves monitoring network performance indicators in a frequency spectrum portion designated for public service users but also shared with non-public service users. When network usage in this portion exceeds a predefined threshold, an updated network configuration is generated. Self-organizing network (SON) tools then transition non-public service users from the congested portion to a different portion of the spectrum, maintaining their ongoing call sessions without interruption. The transition is enforced to prevent users from reverting to the congested portion. Additionally, notifications are displayed on the devices of affected users, informing them of the transition. The system uses SON tools, including engineering and visualization tools, to automate spectrum management, ensuring public service users retain priority access while optimizing overall network efficiency. The approach minimizes service disruptions for non-public service users by preserving their active sessions during the transition.
17. The method of claim 16 , further comprising providing the updated network configuration to a base station of the SON, wherein the base station is in communication with the one or more engineering tools.
The invention relates to self-organizing networks (SON) in wireless communication systems, specifically addressing the challenge of dynamically updating network configurations to optimize performance. The method involves monitoring network performance metrics, such as signal quality, interference levels, and traffic load, to detect deviations from desired thresholds. When deviations are identified, the system analyzes the data to determine the root cause, which may include hardware failures, environmental changes, or traffic pattern shifts. Based on this analysis, the system generates an updated network configuration designed to mitigate the detected issues. This configuration may include adjustments to parameters like transmit power, antenna tilt, or handover thresholds. The updated configuration is then provided to a base station within the SON, which is in communication with one or more engineering tools. These tools may include network management systems, optimization algorithms, or diagnostic utilities that assist in implementing and verifying the changes. The base station applies the updated configuration to improve network performance, ensuring efficient resource utilization and enhanced user experience. The method ensures real-time adaptation to network conditions, reducing manual intervention and improving operational efficiency.
18. The method of claim 17 , further comprising modifying a parameter of the base station with a parameter configurator in communication with the one or more engineering tools, wherein the hindering is based at least in part on the modified parameter.
This invention relates to wireless communication systems, specifically methods for managing interference in cellular networks. The problem addressed is the disruption caused by base stations operating in close proximity, which can lead to signal interference and degraded performance. The solution involves dynamically adjusting base station parameters to mitigate interference while maintaining network efficiency. The method includes monitoring network conditions to detect interference between base stations. When interference is identified, the system determines whether it is caused by a neighboring base station. If so, the system hinders the neighboring base station's ability to interfere by adjusting its operational parameters. This adjustment is performed by a parameter configurator, which communicates with engineering tools to modify the base station's settings. The configurator ensures that the modifications are based on real-time network data to optimize performance. The parameter configurator can adjust various base station parameters, such as transmit power, frequency allocation, or beamforming settings, to reduce interference. The adjustments are made in a way that minimizes disruption to ongoing communications while effectively mitigating interference. The system continuously monitors the network to assess the impact of the modifications and makes further adjustments as needed. This dynamic approach ensures that the network remains stable and efficient even in high-interference environments.
19. The method of claim 16 , further comprising receiving, with the one or more SON tools, registration of the public service user in the first portion of the frequency spectrum, wherein receiving registration of the public service user results in network usage within the first portion satisfying the first usage threshold.
This invention relates to wireless communication systems, specifically managing spectrum usage for public safety and commercial services. The problem addressed is efficiently allocating and monitoring spectrum resources to ensure reliable access for public safety users while optimizing commercial network performance. The method involves dynamically adjusting spectrum allocation between a first portion dedicated to public safety and a second portion for commercial use. A self-organizing network (SON) tool monitors usage in the first portion and compares it to a predefined threshold. When usage exceeds the threshold, the SON tool reallocates spectrum from the second portion to the first, ensuring public safety users have sufficient resources. Conversely, when usage falls below the threshold, spectrum is reallocated back to the commercial portion to maximize efficiency. The method further includes receiving registration of a public safety user in the first portion, which triggers the SON tool to verify if network usage meets or exceeds the threshold. This ensures that spectrum adjustments are made in real-time based on actual demand, preventing congestion and maintaining service quality for critical communications. The SON tool continuously monitors and adjusts spectrum allocation to balance public safety needs with commercial network efficiency.
20. The method of claim 16 , further comprising receiving network information with a consolidation engine in communication with the one or more SON tools, and determining the one or more performance indicators based on the network information.
The invention relates to self-optimizing networks (SON) in wireless communication systems, specifically improving network performance through automated optimization. The problem addressed is the inefficiency of traditional SON tools, which often operate in isolation, leading to suboptimal network performance due to lack of coordination between different optimization functions. The solution involves a consolidation engine that integrates multiple SON tools to enhance network performance. The method includes receiving network information from various sources, such as base stations, user devices, or network management systems. The consolidation engine processes this data to determine performance indicators, which may include metrics like signal strength, latency, or resource utilization. By analyzing these indicators, the engine identifies optimization opportunities and coordinates actions across different SON tools to improve overall network efficiency. The consolidation engine may also prioritize optimization tasks based on real-time network conditions, ensuring adaptive and dynamic adjustments. This approach reduces manual intervention and improves network reliability, capacity, and user experience.
